Class 10.9 Steel Black Zinc Plated Hex Bolts Class 10.9 Hex Head Screws
Products Descriptions
Choose these Class 10.9 steel screws for high-stress applications, such as valves, pumps, motors, and automotive suspension systems.They are at least 25% stronger than medium-strength steel screws. Dimensions meet ISO (formerly DIN) specifications. Length is measured from under the head.
Steel screws should be used in dry, noncorrosive environments. Zinc yellow-chromate plated and zinc-plated steel screws resist corrosion in wet environments. Blue-dyed screws are easy to distinguish. Black ultra-corrosion-resistant-coated steel screws resist chemicals and withstand 1,000 hours of salt spray.
Match the thread spacing of mating components. Coarse threads are the industry standard; choose these screws if you don’t know the pitch. Fine and extra-fine threads are closely spaced to prevent loosening from vibration; the finer the thread, the better the resistance.
